2 Claims. (Cl. 173-269) My invention relates to electrical connectors.

The primary object of my invention is to provide 'an electrical connector for attaching a wire' thereto, wherein the pull-out value for the wire from the connector will be substantially equal to the breaking s rength of the wire itself.

Other objects of my invention are toprovide a connector wherein the wire may be snubbed thereto to give maximum pull-out values.. to provide electrical contact with the wire separable from the mechanical holding means; to provide a connection which will accomplish the foregoing objects with minimum deformation of the wire; to provide a connector body adapted to be compressed about the wire; to provide a connector to which the wire may be snubbed with the minimum strain on the wire; and to provide a onepiece connector adapted to mass productionl Similarly, the outer edges 23 of the two wall sections may be tapered in the opposite direction of the grooves, so as to provide more metal where the wire is completely enclosed, giving the compressed louter surface of the connector body a cylindrical eiect, as shown in Figs. 5 and 6.

. The two grooves of the H-shaped body section may be placed in the same plane as the tongue section, thus eliminating the necessity for the aperture 20. This modiilcation is shown in Fig. 7, wherein the tongue 30 is substantially an extension vof the wall section 3| with wall section 32 separated by web section 33, forming grooves 34 and 35. The wire in grooves 34 and 35 is looped around the end portion 36 of the two grooves, which snubs the wire to the connector body, as

the wall sections 3| and 32 are compressed about the wire therein.

In Fig. 8 there is illustrated a further modification in which the wire is produced about a circular rivet-shaped extension tothe connector body. Here the tongue section 40 is an extension of the sheet metal plate 4I in which a rivet-like section 42 is'produced by drifti the metal outwardly Fig. 4 i s a sectional view taken along line 4 4 of Fig. 5.

Fig. 5 is a front view of my connector attached 'to a wire.

vided with a, terminal tongue II, perforated at I2, and an extending connector body I3, which is H-shaped as shown in Fig. 3, providing two wall sections I4 and I5 separated by a web section I6, forming two longitudinal grooves I1 and I8, into which the wire is positioned.

In the connector neck I9 between the body I3 and tongue II, an aperture 20 lis formed through which the wire is inserted.

As shown in Figs. 2 and 3, the web section I6 is slightly tapered, which permits the end 22 of wire 2 l, shown in Fig. 3, to be looped through the aperture 20, and positioned in the grooves so asto occupy the minimum diameter when the connector body wall sections are compressed together as shown in Fig. 4.

through the center of the' plate. The ilar'ed ends 43 of the drifted metal produce a circumferential groove 44, into which the wire is positioned. A small cut-out 45 may be formed into one side of the ared end 43, for permitting the entrance and exit of the looped wire. The flared ends are turned in a rivet compressing machine which circumferentially compresses the wire.

- I have thus provided a connector body that can be made by various methods, all forms providing means for snubbingl the wire to the connector wall and compressing the wall about the wire to establish the maximum electrical contact.

I have thus described my invention, but I de-A sire it understood that it is not confined to the particular forms or uses shown and described, the same being merely illustrative, and that the invention may be carried out in other ways without departing from the spirit of my invention, and, therefore, I claim broadly the right to employ all equivalent instrumentalities coming within the scope of the appended claims, and by vmeans of. which, objects of my invention are accomplish these results.

the grooves being compressible about the wire to secure the wire therein; said grooves converging at one end of the connector body, and diverging at the other end of the connector body aclJacent l the aperture in the terminal plate.

2. A wire connection comprising in combination an H-shaped body the open portions of the H-shaped body constituting a pair of substantially longitudinal grooves extending through said body. a looped wire contained therein, one end of the H-shaped body being at to form a terminal plate extending integrally from said body at the looped end of the wire. said wire tightly looped with the groovesin said body so as not to leave an open space between the wire and the body, the

. metal of said body compressed around the wires to form a cylindrical shape.
